' parent panels 13. The doors 12 constitute ventilating portsforhthe vestibule, when both-doors7 .are in closed position.v The.

door 7 is adapted to swing and remain transversely' of the car as shown atthe right of Fig. 2 and when in this position the step 11 is extended'as shown, or may swing-to the positionshown at theleft of Fig. 2-when. the Stepll is withdrawn and the car. closed 'on this'side. When the door 7 is in closed position, it swings against the j'amb. 6 and makes a tight joint.

The mechanism for controlling the doors and which also controls the steps is as follows: A rail 14 is secured to thecar body and upon which is mounted a'plate 15 pro- 'vided with a pair of vertica1ly;extending parallel rods 16, 1-7 which also extend below the floor 1. The up er end of each, of the receive a handle. 18 by means of which either rods 16 and 17 is pre erably squared-so as to of therods may be'conveniently rotated.
